Mafia 60. Nonsense, mayhem, and a few artifacts.

And one more thing: if the Winner was a baron, then the Cop wasn't part of the mafia; no mafia role would suit him. In that case, he was most likely a maniac, or more precisely, a Sorcerer.

Yeah, based on the description of the Cop's execution, Sorcerer fits, because it's awkward to execute someone who gives them artifacts, but at first, I thought it was a female trickster, like it's awkward to execute a girl.
